An issue was discovered in Sielco Sistemi Winlog Lite SCADA Software, versions prior to Version 3.02.01, and Winlog Pro SCADA Software, versions prior to Version 3.02.01. An uncontrolled search path element (DLL Hijacking) vulnerability has been identified. Exploitation of this vulnerability could give an attacker access to the system with the same level of privilege as the application that utilizes the malicious DLL.

Sielco Sistemi Winlog Pro SCADA before 2.07.18 and Winlog Lite SCADA before 2.07.18 do not validate the return value of the realloc function, which allows remote attackers to cause a denial of service (invalid 0x00 write operation and daemon crash) or possibly have unspecified other impact via a port-46824 TCP packet with a crafted negative integer after the opcode. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-4358.

Sielco Sistemi Winlog Pro SCADA before 2.07.17 and Winlog Lite SCADA before 2.07.17 do not validate the return value of the realloc function, which allows remote attackers to cause a denial of service (invalid 0x00 write operation and daemon crash) or possibly have unspecified other impact via a port-46824 TCP packet with a crafted positive integer after the opcode.

Array index error in Sielco Sistemi Winlog Pro SCADA before 2.07.17 and Winlog Lite SCADA before 2.07.17 might allow remote attackers to execute arbitrary code by referencing, within a port-46824 TCP packet, an invalid file-pointer index that leads to execution of an EnterCriticalSection code block.

Multiple directory traversal vulnerabilities in Sielco Sistemi Winlog Pro SCADA before 2.07.17 and Winlog Lite SCADA before 2.07.17 allow remote attackers to read arbitrary files via port-46824 TCP packets specifying a file-open operation with opcode 0x78 and a .. (dot dot) in a pathname, followed by a file-read operation with opcode (1) 0x96, (2) 0x97, or (3) 0x98.

TCPIPS_Story.dll in Sielco Sistemi Winlog Pro SCADA before 2.07.18 and Winlog Lite SCADA before 2.07.18 allows remote attackers to execute arbitrary code via a port-46824 TCP packet with a crafted negative integer after the opcode, triggering incorrect function-pointer processing that can lead to a buffer overflow. NOTE: some of these details are obtained from third party information. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-4354.

TCPIPS_Story.dll in Sielco Sistemi Winlog Pro SCADA before 2.07.17 and Winlog Lite SCADA before 2.07.17 allows remote attackers to execute arbitrary code via a port-46824 TCP packet with a crafted positive integer after the opcode, triggering incorrect function-pointer processing that can lead to a buffer overflow. NOTE: some of these details are obtained from third party information.

Stack-based buffer overflow in RunTime.exe in Sielco Sistemi Winlog Pro SCADA before 2.07.17 and Winlog Lite SCADA before 2.07.17 allows remote attackers to execute arbitrary code via a crafted port-46824 TCP packet that triggers an incorrect file-open attempt by the _TCPIPS_BinOpenFileFP function, a different vulnerability than CVE-2012-3815. NOTE: some of these details are obtained from third party information.

Buffer overflow in RunTime.exe in Sielco Sistemi Winlog Pro SCADA before 2.07.18 and Winlog Lite SCADA before 2.07.18 allows remote attackers to execute arbitrary code via a crafted packet to TCP port 46824. NOTE: some of these details are obtained from third party information.

Buffer overflow in Sielco Sistemi Winlog PRO before 2.07.09 and Winlog Lite before 2.07.09 allows user-assisted remote attackers to execute arbitrary code via invalid data in unspecified fields of a project file.

Stack-based buffer overflow in Sielco Sistemi Winlog Pro 2.07.00 and earlier, when Run TCP/IP server is enabled, allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a crafted 0x02 opcode to TCP port 46823.
